The Dutch semiconductor equipment maker says reports involving one of its highly restricted EUV systems are unfounded and that its machines remain closely tracked worldwide. ASML, the Dutch company behind some of the world's most advanced chipmaking equipment, has rejected claims that one of its extreme ultraviolet, or EUV, lithography machines may have made its way into China.
The allegation reportedly drew attention from the US administration, raising questions about whether an EUV system could have bypassed strict export controls imposed by the Netherlands and the United States.
ASML, however, has firmly denied the suggestion.
The company said there is no indication that any of its EUV machines are located in China and described similar rumours in the past as inaccurate, damaging and unsupported by evidence.
Why ASML's EUV Machines Matter
ASML does not manufacture computer chips itself. Instead, it builds highly specialised lithography systems used by leading semiconductor companies to produce advanced chips.
Its EUV machines are particularly important because they are used to create the smallest and most advanced chip designs. These chips can be found in high-performance smartphones, artificial intelligence systems, data centres, graphics cards and other advanced technologies.
Because of their strategic importance, EUV machines are subject to some of the tightest export controls in the global technology industry.
China has not been allowed to receive ASML's EUV systems under existing export restrictions, making any claim of one reaching the country a major concern for governments and the semiconductor industry.
ASML Says It Can Track Its Systems Closely
ASML reportedly told US officials that the claim was unfounded and that it has no evidence of an EUV machine being present in China.
The company is believed to have circulated an internal document among officials in Washington stating that there was no indication of any ASML EUV system operating in the country.
ASML also pointed out that its machines are not small or easy to move quietly.
A fully assembled EUV lithography system consists of around 100,000 components and can weigh roughly 180 tonnes. Transporting one requires major planning, specialised logistics and multiple shipments. It is not the type of equipment that can simply disappear without leaving a significant trail.
The company has also said that its systems can be monitored and tracked, which makes it difficult for an entire EUV machine to be moved without ASML being aware.
Why Smuggling or Rebuilding an EUV System Would Be Extremely Difficult
The complexity of an EUV machine is one of the main reasons ASML has dismissed the speculation.
These systems combine advanced optics, lasers, vacuum technology, precision mechanics, software and highly specialised components produced by suppliers around the world. Even the smallest part can require years of research and engineering.
ASML has consistently maintained that its EUV technology cannot realistically be recreated simply by obtaining spare parts, scrap equipment or individual components.
Putting together a working EUV system would require not only the hardware, but also deep technical knowledge, specialised facilities, highly trained engineers and access to technologies that remain tightly controlled.
Export Controls Remain a Sensitive Global Issue
The claim comes at a time when semiconductor technology is becoming increasingly tied to national security and global trade policy.
The United States, the Netherlands and other allied countries have introduced restrictions on the export of advanced chipmaking equipment to China. The aim is to limit access to technology that could support advanced military systems, artificial intelligence development and high-performance computing.
ASML has repeatedly said it recognises the national security concerns behind these export regulations and is committed to following the rules set by governments where it operates.
The company has also adjusted its business practices as export-control requirements have evolved, including restrictions involving certain advanced systems and servicing arrangements.
What the Dispute Shows About the Chip Industry
Even without public evidence that an EUV system reached China, the situation highlights how closely governments now watch advanced semiconductor equipment.
EUV machines have become one of the most strategically important technologies in the world. They are essential to producing the most advanced chips, yet only one company currently makes them at commercial scale.
That gives ASML an unusually critical position in the global technology supply chain.
Any report involving the possible movement, misuse or unauthorised transfer of an EUV machine is therefore likely to attract intense scrutiny from governments, security agencies and major chipmakers.
Final Thoughts
ASML's response is clear: it says there is no evidence that one of its EUV machines has reached China, and it maintains that such a system would be exceptionally difficult to transport, hide or reproduce.
The episode reflects the growing tension around semiconductor technology, export controls and global competition for advanced computing capabilities. As chips become more central to artificial intelligence, defence, communications and consumer technology, the companies that build the tools to manufacture them will remain under intense international attention.
